I recall a lot of discussion awhile back about some interlace artifacts remaining in the GOUT transfer. A lot of filters were tossed around as being useful, but what is available has improved.

I don't see a specific filter being used for cleaning that, and they are probably removed as a by-product of something else (probably the anti-aliasing), but I'd like to suggest one more thing:

TFM(pp=2,clip2=TempGaussMC_beta2(edimode="nnedi2").SelectEven)

TempGaussMC with nnedi2 will bring most computers to their knees (I think I can render 1 frame every 30 seconds with it), but TempGaussMC turns on ONLY when TFM decides a frame has interlace artifacts. The rest of the time it does nothing.

Image quality is pretty much a perfect extrapolation for these frames.
